Optimising Post-Curing Conditions for Dental 3D Printing: Workflow Efficiency, Surface Quality and Biocompatibility

This webinar examines how vacuum post-curing may influence curing time and cytotoxicity in 3D-printed dental resins, drawing on research findings to discuss its potential role in more efficient dental workflows.

Post-curing is an essential step in dental 3D printing, influencing the properties of printed resins and their suitability for clinical use. Optimising this step requires consideration of both processing time and material performance, including biological responses.

This webinar examines vacuum post-curing as a potential approach to improving workflow efficiency. Prof. Sheng-Wei Feng will discuss the role of oxygen inhibition in resin polymerisation and review how the post-curing atmosphere may influence material properties. Research findings on curing time and cytotoxicity will provide a basis for exploring the potential benefits of vacuum curing in dental 3D printing.

The session will also address why post-curing protocols need to be validated for specific resins and equipment. Participants will gain a clearer understanding of how to interpret the available evidence and assess opportunities to simplify post-curing workflows while maintaining the required material performance.

Learning objectives

By the end of this webinar, participants will be able to:

• Explain the role of oxygen inhibition in the post-curing of 3D-printed dental resins.
• Describe how vacuum post-curing may influence curing time and material properties.
• Interpret cytotoxicity findings and distinguish them from a broader assessment of biocompatibility.
• Identify key considerations for resin- and equipment-specific validation of post-curing protocols.
• Assess the potential role of vacuum curing in simplifying dental 3D printing workflows.
